For best performance, fill both memory slots, installing an equal memory module in each slot.

Removing or installing memory

Warning: The internal components of your MacBook Pro can be warm. If you have been using your MacBook Pro, wait ten minutes after shutting down the computer to let the internal components cool before continuing.

Step 1: Remove the bottom case

Shut down your MacBook Pro. Disconnect the power adapter, Ethernet cable, USB cables, security lock, and any other cables connected to the MacBook Pro to prevent damaging the computer.

Turn over your MacBook Pro and remove the ten (10) screws that secure the bottom case. Because the screws are different lengths, note the screw lengths and locations so you can replace the screws correctly. Put them aside in a safe place. Lift off the case and place it to the side.

Touch a metal surface inside the computer to discharge any static electricity from your body.

Step 2: Remove existing memory (if present)

Push the levers on the sides of the memory module in an outward direction to release the module from the memory card slot. The memory pops up at an angle. Before removing it, make sure you find the half-circle notches. If you don’t, try pressing the levers outward again.

Hold the memory module by its notches and remove it from the slot.

Remove the other memory module.Important: Hold the memory modules by their edges, and do not touch the gold connectors.

Step 3: Install memory

Align the notch on the gold edge of the module with the notch in the lower memory slot.

Tilt the card and push the memory into the slot.

Use two fingers with firm, even pressure to push down on the memory module. There should be a click when you insert the memory correctly.

Repeat this procedure to install an additional memory module in the top slot. Press down on the module to make sure it is level.

Note: Make sure you install the memory according to this illustration, with the gold contacts inserted almost completely into the connector.

Step 4: Replace the bottom case

Replace the bottom case. Replace and tighten the ten screws you removed earlier, making sure to put the different length screws in their proper locations.

For best performance, fill both memory slots, installing an equal memory module in each slot.

Use two fingers with firm, even pressure to push down on the memory module. There should be a click when you insert the memory correctly.

Repeat, if necessary, to install an additional memory module in the top slot. Press down on the module to make sure it is level.Note: Make sure you install the memory according to the illustration below, with the gold contacts inserted almost completely into the connector.

Step 6: Replace the bottom case

Replace the bottom case. Replace and tighten the eight screws.

Step 7: Replace the battery

To replace the battery, make sure the latch is in its open position. Hold the battery at an angle and slide the lipped edge of the battery below the brackets on the outside edge of the battery bay. Gently press the battery down.

Step 8: Replace the access door

With the latch in the open position replace the access door, making sure it is level with the bottom case of your MacBook Pro, and press the latch into the closed position.

You can add two 4 GB memory modules for a maximum of 8 GB of memory. For best performance, fill both memory slots and install an identical memory module in each slot.

Refer to this table for the maximum amount of memory that can be recognized by these notebook computers:

2 GB

MacBook Pro, MacBook Pro (17-inch), MacBook Pro (15-inch, Glossy)

3 GB

MacBook Pro (15-inch and 17-inch Core 2 Duo)Note: These models will support only 3 GB total memory. If you want to maximize the amount of SDRAM in your computer, install a 2 GB SO-DIMM in one slot and a 1GB SO-DIMM in the other.

Removing or installing memory

You will need to remove the battery before installing additional memory and reinstall the battery after installing the memory. The following procedure includes all the necessary instructions for both parts of the process.

Warning: The internal components of your MacBook Pro can be warm. If you have been using your MacBook Pro, wait ten minutes after shutting down the computer to let the internal components cool before continuing.

Step 1: Remove the battery

Shut down your MacBook Pro. Disconnect the power adapter, Ethernet cable, and any other cords connected to the MacBook Pro to prevent damaging the computer.

Turn the computer over.

Locate the battery release latches on each side of the battery.

Slide both latches up. The battery should pop up slightly.

Lift the battery out.

Step 2: Remove the memory door

Using a Phillips size 00 screwdriver, unscrew the memory door and remove it from the battery bay of your computer. Depending on the model of your MacBook Pro, you may have three or four screws.

Touch a metal surface inside the computer to discharge any static electricity from your body.

Step 3: Remove existing memory (if present)

If you need to remove a memory card—for example if you are replacing it or if you need to get past the memory in the top slot to access the bottom slot—you can remove the card by spreading the tabs on each side of the card away from the notches in the memory card. The card should pop up slightly. Lift the memory card to about a 25-degree angle and then gently slide the card out of the memory slot.Important: Hold the memory modules by their edges; do not touch the gold connectors.

Step 4: Install memory

Insert the new memory card at a 25-degree angle. Line up the notch in the card with the small tab in the memory slot and slide the card into the slot until the gold edge is almost invisible. Firmly press the memory card into the memory slot. You might feel some resistance.

Gently spread the small tabs in the memory slot away from the notches and push the memory card down until the two tabs on either side of the card lock into place.

Insert any additional memory into the second slot.Note: Make sure you install the memory according to the illustration below, with the gold contacts inserted almost completely into the connector.

Step 5: Replace the memory door

Replace the memory door, and make sure the door is lying flat before you screw it back into place.

Step 6: To insert the battery

Place the bottom edge of the battery into the battery compartment at an angle, as shown below.

Gently press the top edge of the battery down until the battery latch locks into place.

After installing additional memory, you should confirm that the computer recognizes the new memory. To check the computer’s memory:

Start up your computer.

When you see the Mac OS X desktop, choose the Apple () menu from the upper-left menu bar, then choose About This Mac.

The total memory includes the amount of memory that originally came with the computer plus the new memory you added, or if all the memory has been replaced, the new total for that memory. For detailed information about the amount of memory installed in your computer, open System Profiler by choosing Apple () and then About This Mac. Then, click More Info and then Memory from the Hardware section that appears in System Profiler.

If your computer doesn’t recognize the memory or doesn’t start up correctly, confirm that the memory you installed is compatible with your MacBook Pro and that it is installed correctly by reseating the memory.
